Recently replaced a legacy SOAP application with REST service (Rest service is hosted in apigee; SOAP service is not). Would like to create a SOAP proxy in apigee that takes the incoming SOAP call, converts it to REST, then converts the rest response to SOAP for the reply.

Example:

In coming SOAP request -

<LookupDetails>
  <MethodParameters>
    <request>
      <IdentificationNumber>12345678</IdentificationNumber>
      <RequestingUserName>USER</RequestingUserName>
      <RequestingUserPassword>PASSWORD</RequestingUserPassword>
      <RequestingUserClient>CLIENT</RequestingUserClient>
      <RequestingUserRole isNull="false"/>
      <APIKEY isNull="false"/>
    </request>
  </MethodParameters>
</LookupDetails>

Need the proxy to validate the user name and password then convert request to REST and do a post to my existing REST API with the request body below.

<Search xmlns="http://schema.search.com">
  <Fields>
    <string>DetailList</string>
  </Fields>
  <Id>
    <string>12345678</string>
  </Id>
</Search>

I would appreciate any assistance you can provide.

Yes, this is a really common thing to do with Apigee Edge.

If you give me the REAL soap message, I can produce an example that does basically what you want, I think.

If you'd prefer to do it yourself, then here's what I suggest:

use the ExtractVariables policy to extract the various fields from the inbound XML
verify the user credentials (however you'd like to do that) . Maybe via a ServiceCallout policy.
Maybe with an LDAP call. Maybe a different way.
upon successful user authentication, use XSLT to produce the payload to be sent to the backend.
POST to the REST backend.
With the response, apply an XSLT to produce a SOAP envelope + response
send that SOAP response to the original caller

This is basically the reverse of the "SOAP-to-REST proxy" pattern, something that is done really commonly in Apigee Edge.

Is there a sample available to create a SOAP front end for a REST service?
